### Constants

[`SCNBillboardAxisX`](/documentation/SceneKit/SCNBillboardAxis/X)

[`SCNBillboardAxisY`](/documentation/SceneKit/SCNBillboardAxis/Y)

Align an affected node such that its y-axis is always parallel to that of the view, leaving it free to rotate otherwise.

[`SCNBillboardAxisZ`](/documentation/SceneKit/SCNBillboardAxis/Z)

Align an affected node such that its z-axis is always perpendicular to the viewing plane, leaving it free to rotate otherwise.

[`SCNBillboardAxisAll`](/documentation/SceneKit/SCNBillboardAxis/all)
